过收敛点上具有闭支撑的上同调

Cohomology with closed support on the overconvergent site

David Zureick-Brown

摘要:

利用SGA的开/闭子拓扑的概念,我们定义了在过收敛点上的闭子概形中的上同调支撑的概念,并证明了这与经典的闭子概形中的刚性上同调支撑的概念是一致的.

英文摘要:

Using the notions of open/closed subtopoi of SGA, we define a notion of cohomology with support in a closed subscheme on the overconvergent site, and show that this agrees with the classic notion of rigid cohomology support in a closed subscheme.
